Jeff, you will probably need a pre-amp with the K3. My experience of 6m over the past 3 or 4 years with a 4 ele quad is that many signals are very weak and the K3 lacks the sensitivity to deal with them unless you either add a pre-amp or have a high level of local noise masking those signals.
My K3, serial 80, gives 10 dB SINAD at -126 dBm in a 400 Hz bandwidth using the internal pre-amp. Adding an external Advanced Receiver Research P50VDG pre-amp via the KXV3 RX ANT IN/OUT sockets improved the sensitivity by 10 dBm which is a huge improvement for weak signal work. The Elecraft pre-amp is a similar specification and should give similar results. For those who compare figures using MDS the "with and without" figures in a 400 Hz bandwidth are -136 dBm and -146 dBm. Image rejection is marginal at 62 dB. Power output on 6m is fine and the worse case harmonic is -60 dB. 73 Dave, G4AON --------------------------------- Hi everyone, Sorry to trouble you all again but I'd like to find out more on the K3's 6M performance as very little seems to be mentioned on the Elecraft website. <SNIP> Jeff Cochrane - VK4BOF ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
